IMPROVEMENT IN CORN-SHELLERS.

Specification forming part of Letters Patent No. 158,71 1, dated J annary 12, 1875; application filed July 24, 1874.

To all whom it may concern:

Be it known that I, LoRA B. HOTT, of Worcester, county of Worcester and State of Massachusetts, have invented certain Improvements in Gorn-Shellers. The following description, taken in connection with the accompanying plate of drawings hereinafter referred to, forms a full and exact specification, wherein are set forth the nature and principles of the invention, by which the same may be distinguished from others of a similar class, together with such parts thereof as are claimed as new, and are desired to be secured by Letters Patent of the United States.

My invention relates to that class of cornshellers in which a toothed disk is made to operate in conjunction with a presser-board, commonly known asV disk-shellers, and the nature thereof consists in certain improvements upon the patent granted to De Witt C. Sterry, dated September 3, A. l). 1872, and numbered 131,129.

In the accompanying plate of drawings, in which corresponding parts are illustrated by similar letters, Figure lis a longitudinal elevation. Fig. 2 is a tranverse vertical section, taken on .the line a: a: a w, Fig. 1. Fig. 3 illustrates the interior of the casin g, the disk-plate being removed for that purpose.

A designates the casing which surrounds the disk-plate, cast in one piece and rigidly attached to the frame B. The said casing is provided with a spout, e, through which the shelled corn falls. E designates the hopper, into which the ear to be shelled is inserted. The said hopper is provided with a tongue, d, which accurately lits the interior surface of the said hopper, and extends from the top of the same to a point at or near the shaft lc. In shelling the largest-sized corn the said tongue is not used, but iny adapting the machine to corn grown north of forty degrees of latitude, or common corn, it becomes necessary to diminish the diameter of the hopper, and for this purpose the tongue is introduced and held firmly in position by the screw g, or in any other proper way. By the use of this device the machine may be adapted to corn of any size.

The general construction of the disk h, shaft k, and spring m is the same as that ot' similar devices described in the Said patent to De Witt (l. Sterry-that is to say, from the center of the disk h, and forming a part of the same casting, a shaft, la, passes through the presser-plate u and cross-bar of frame B. Upon the end of the said shaft, and between the same and the frame,is arranged the sprin g m, which is held in position by the nut p and jam-nntp in such a manner as to allow the revolving disk to adjust itself to the size of the ear. q designates a plate attached to the frame and provided with a cylindrical projection, in which is cut an annular slot, s, for the reception of the end of the spring m. Upon the surface of the presser-plate is cast a projection, w, of curvilinear form. The said projection commences at a point on the right side of the hub or bearing of the shaft, and extends to a point situated at about one-third of the distance from the shaft to the extreme left of the casing. The office ofthe said projection is to cause the ear to pass around the casing, from the bottom of the hopper to the opening at the left of the casing, at a greater radial distance from the center of the revolving disk than it would otherwise. A somewhat similar projection is cast upon the presser-plate at ac for thepurpose of guiding the end of the ear. Between the projections w and x arelarranged a series of corrugations, z, of curvilinear form, which remove the corn from the cob without tearing or mashing the cob.

Having thus described the construction and operation of my invention, I will indicate in the following clauses whatI claim, and desire to secure by Letters Patent-thatis to say:

1. In a disk corn-sheller, the presser-plate provided with the curvilinear projection w, commencing at a point on the right side of the hub of the shaft and extending to a point situated at or about one-third of the distance from the shaft to the extreme left of the casing.

2. In a disk corn-sheller, the presser-plate provided with the project-ions fw and w, as and for the purposes described, whereby the Q t y 158,911

orn is caused to pass around the casing at a In testimony that I claim the foregoing greater radial distance and the end of the ear have hereunto set my hand this 21st day of is ground. J uly, 1874.
